In June 2016, under Japanese presidency, G7 Leaders endorsed “G7 Ise- Shima Principles for Promoting Quality Infrastructure Investment,” which has crystalized as definition of quality infrastructure investment.

The Principles consist of five key elements covering governance, economic impact, social and environmental impacts, alignment with economic development, and the need to enhance effective resource mobilisation.
